Some time ago, a Ghana customer bought a large quantity of phosphoric acid for food processing from our company. The food grade phosphoric acid has higher requirements on production method and purity. So we sent the technical specifications of the product to the client and told him that it is absolutely in full compliance with food safety standards. After the testing, the customer speak highly of the quality of our products. In addition, as a reliable manufacturer, we can also produce fertilizer grade phosphoric acid. If you have any need, please feel free to contact us for more details and price.
